Not quite... actually, there are several excellent free RE tools
around. But I don't know of any good RE tools, free or commercial,
that support Unicode. 16-bit as opposed to 8-bit characters do
change the scope of the problem. It's not just regexp, we have
some tricky work to do if we want to do *anything* inside an
element, e.g. token or even character counting, in the
internationalized environment. - Tim
